WATER-ELEVATING DEVICE.

SPECIFICATION forming part of Letters Patent N0. 779,845, dated January 10, 1905.

Application filed July 8, 1904. Serial No. 215,826.

To all whom, it may concern.'

Be it known that I, VICTOR P. HAMMER, a citizen of the United States, residing in the 1 city of Washington, in the District of Columbia, have invented new and useful Improvements in VVater-Elevating Devices, of which the following is a specification.

This invention relates to water-elevating devices.

One object of the invention is to improve the devices commonly used for hoisting the well-buckets, the improvement aiming principally to enable a plurality of well-buckets to be employed in such manner that when a full bucket is raised from the well an empty bucket is simultaneously lowered thereinto.

A further object of the invention is to improve the construction of the well-buckets and well-casing in such manner that the buckets may be emptied easily and quickly without the necessity of removing them from the well or tilting them in order to pour the water therefrom.

Further minor objects of the invention will be apparent from the following detail description.

The first object of the invention Iis attained, preferably, by means of a pair of operatingpulleys having adjacent thereto a plurality of pairs of idle pulleys, a pair of flexible elements or ropes passing over one pair of the idle pulleys,underneath the operating-pulleys, and over the other pair of idle pulleys and having a well-bucket connected with each end thereof, whereby when one of the buckets is raised from the well the other is simultaneously lowered thereinto, the pair of eXible elements being' used in order to prevent the bucket from dropping in the event that one of the elements should break.

The second object of the invention is attained, preferably, by employing a novel form of well-bucket having in the lower portion thereof a valve and a trough pivotally mounted within the well-casing in such manner that when a full bucket has been raised the pivotally-mounted trough may be partially rotated until it is disposed beneath the bucket, the construction of the valve and of the pivoted trough being such that the Valve is raised sufficiently to permit the contents of the bucket to drain into the trough.

In addition to the combination and arrangement of parts above outlined the invention also resides in the particular combination and arrangement of parts and in the precise details of construction hereinafter described and claimed as a practical embodiment of the invention.

In the accompanying drawings, forming part of the specification, Figure 1 is a side elevation of a well-casing provided with the improvements of the present invention. Fig. 2 is a vertical section thereof. Fig 3 is a horizontal section on the line 3 3, Fig. 2. Fig. 4 is a vertical section on the line 4 4, Fig. 2. Fig. is a view similar to Fig. 4, showing a dierent method of attaching the well-ropes to the bucket. Fig. 6 is a vertical section of a bucket adapted for use in connection with the invention, and Fig. 7 is a plan view of said bucket.

Like reference numerals indicate corresponding parts in the different figures of the drawings.

The reference-numeral l designates a wellcasing which may be of any suitable form and construction, a plurality of apertures 2 being' formed therein for the purpose of ventilation. Journaled in suitable brackets 8 on the upper surface of the casing l is an operating-shaft 4, which is rotated in any suitable manner, as by means of a crank 5. Rigidly fastened upon the shaft 4 is a toothed wheel 6, with which cooperates a double-ended pawl 7, pivoted at 8 to one of the brackets 3. Formed on the double-ended pawl7 is a guideway 9, which preferably is in the form of a. tube having closed ends. Located in the guideway 9 is a suitable gravity element, such as a ball 10, which is adapted to roll from one end of the guideway to the other. By tilting the double-ended pawl 7 with the hand the gravity member l0 will roll to the opposite end of said pawl, and thereby cause it to bear against the opposite periphery of the toothed wheel 6.

A pair of pulleys,such as l1,is mounted upon the shaft 4. The periphery of each pulley Journaled ll preferably is grooved as usual.

IOO

on the brackets 3 above the shaft 4 is a pair of shafts 12, each of which carries a pair of idle pulleys, such as 13, the periphery of each of which guide-pulleys is grooved in a manner similar to pulleys 11. Each of the wellbuckets 14 preferably is suspended by means of two iiexible elements or well-ropes 15, said well-ropes passing over one set of idle pulleys 13, under the operating-pulleys 11, and over the other set of idle pulleys. By reason of this arrangement the rotation of the operatingshaft 4, with its pulley 11, in one direction causes one of the buckets 14 to be raised from the well and the other bucket to be simultaneously lowered thereinto. When the shaft 4 is rotated in the opposite direction, the movement of the buckets is reversed. It will be observed that by munipulating the double-ended pawl 7 each time the crank 5 is turned accidental reverse movement of the shaft 4 is prevented, whereby it is impossible for a filled bucket accidentally to descend into the well.

Each of the pulleys 11 and 13 is formed with a hub 16, having therein a perforation 17, adapted to receive a suitable pin or bolt. (Not shown.) The shafts 4 and 12 are also formed with perforations 13, with which the perforations in the hubs 16 are adapted to register. By means of this construction the pulleys 11 and 13 may be adjusted longitudinally upon the shafts 4 and 12, and held against rotation thereon by means of any suitable pins or bolts passed through the hub`16 and shaft-perforations 18.

Each of the buckets 14 is provided with a handle having a plurality of attaching-loops 19, 19, and20. In Fig. 4 the well-ropes 15 are shown connected with the attaching-loops 19, in which case the pulleys 11 and 13 are adjusted away from each other upon their shafts. wWhen it is desired to attach the wellropes 15 to the loop 20, as shown in Fig. 5, the pulleys 11 and 13 are adjusted toward each other upon their shafts. 3y providing two well-ropes in the manner described the wellbuckets are prevented from falling into the well, one of the ropes serving to hold the bucket in the event that the other rope breaks. By providing pulleys which are longitudinally adjusted upon their shafts it is possible to use buckets which have only the central attaching-loops 20.

Each of the buckets 14 is formed in its bottom with a valve-seat 22, on which is mounted a valve 23, provided with a depending pin or projection 24. A screen or perforated element 25 is disposed over the valve 22 and serves not only to prevent the entrance of large objects into the bucket while it is being filled at the bottom of the well, but also to hold the valve always in cooperative relation with its seat. It will be understood that each of the buckets 14 is constructed, preferably, of

metal, or, if constructed ofI wood, is suitably weighted, so that when it is lowered into the well the valve 23 will be raised in order that the bucket may be filled.

Pi votall y mounted at each end of the casing 1 is a trough, such as 26. Each of the pivotally-mounted troughs 26 is formed with a contracted spout 27 and an enlarged entranceopening 28. The entrance-opening 28 of each, trough is covered by a perforated diaphragm or screen 29, a pin or brace 30 being located at the central portion of said perforated diaphragm and resting against the bottom of the trough to prevent any sagging of the diaphragm. When the pivotally-mounted trough is raised into horizontal position, the diaphragm 29 above the brace 30 strikes against the depending projection on the valve 23 and raises said valve, whereby the contents of the bucket drain off through the trough 26, from which they pass into a stationary trough 31, the contracted spout 32 of which terminates outside the well-casing, as shown in Fig. 1` Each of the troughs 26 is pivotally mounted by being connected with a shaft 33, journaled on the casing 1. Each of the shafts 33 is provided on its outer end with a crank 34, formed with a shoulder 35, adapted to be engaged by a pivoted pawl 36, by means of which the trough may be held in horizontal position -when so desired in order to permit the contents of a bucket to drain off.

The operation of the improved device will be apparent from the foregoing description, in connection with the drawings. After a full bucket has been raised from the well and an empty bucket simultaneously lowered thereinto one of the cranks 34 is operated t0 raise the pivotally-mounted trough, and thus permit the contents of the bucket to be drawn off through the stationary trough 31, as shown clearly in Fig. 2.

A suitable door 37 is provided in the side of the well-casing 1 to permit the removal or replacement of the buckets 14 when so desired.

Having thus described the invention, what is claimed as new is- 1. The combination with a well-casing of brackets carried thereby an operating-shaft journaled in the brackets, apair of idle shafts journaled in the brackets, a pair of longitudinally-adjustable operating-pulleys on the operating-shaft, a pair of longitudinally-adjustable idle pulleys on each of the idle shafts, a pair of flexible elements passing over one pair of idle pulleys, under the pair of operating-pulleys, and over the other pair of idle pulleys, and a bucket suspended from each end of the pair of flexible elements, said bucket having means for attaching the ropes at the sides or the center thereof.
